SASH HAVING RESTLIENT EDGE PORTIONS Filed Dec. 19, 1928 INVENTORATTORNEY Patented Mai-.24, 1931 HA RY E. CAMPBELL, or BALTIMORE, A YL NDsAsx-I HAVING RES'ILIENT EDGE PORTIONS .Application filed Decemberl,1928. Serial No. 326,938.

In windows of the type in which the jambs have verticalopenings in theirinnerface behindwhich are enlarged chambersand the sashes have plateswhich extend through said '5 openings and strike against the backs ofthe chambers to limit transverse movement of the sashes, difiicultiessometimes occur due ,to the jamb frame being distorted while beingerected, which means that the sashes have to m be provided with'someform of adjusting device such asshown in my earlier Patent No.1,502,644dated July 22, 1924, and these adjusters have to be properlyset after the window frames are installed. 'Accordingto 1 the presentinvention I overcome this difliculty by forming the sashes with stifi.but resilient edges. To accomplish this result a U-shaped member isslipped over the edge iof the sash so that it forms substantially acontinuation of the sash plate. This U- shaped member is held to thesash in such a Waythat itmoves vertically with the sash but is permittedto movelaterally-relative to the sash. Within the Urshaped member ispositioned a resilient member bent into what may best be described as aWavy formation. Such member is held in place by the sides of theU-shapedmember and tensionsthe edgeof the U-shaped member away fromtheedge of the sash plate. With such a construction a certain amount ofresiliency is given to the .plate 12 and is held in member 18vfits'around the edge of the plate 12, and within the U-shaped member 18is positionedthe member-2O which is flat in the plane of the sashplatebut is formed in waves to-tension memberlS away from the edge of theplate 12. In the example here shown member 20 is, provided with a bottomhook 22 to support the bottom of U-shaped member 18, and at the topisbent'over to form the projection 24 which extends over the top ofplace by the sash chain 26.

having the sash plate a stifi, substantially straight member tends toprevent it from catching on inequalities in the jamb parti tion againstwhich it rubs.

This invention can readily be understood. .Jy reference to theaccompanying dmZ/wing illustratingthe same, in which Fig. I, is a faceview of a sash with the jamb partition against which it strikes shown insection as indicated by linel-l of Fig. 3; Fig. 2 is a i 45 perspectiveviewof the resilient member, and
